she was no accessory kaldin. And it Jeremy if guilty would have known that to well. And I think Julie did too. Bamber would know he would have to cater to Julie's every whim and beckon call if the police had always accepted the initial story. He would have been on knife edge, you would expected him to be at her side constantly, taking close interest. When in reality it appears the exact opposite took place
I'm not saying she was an accessory, but Jeremy might have thought of her that way. According to her, he had often spoken about killing his family, and she did nothing to dissuade him, so he might have interpreted that as her going along with it. She covered up for him afterwards, and lied by omission in her first statement. She could have been charged with assisting an offender at least, so he might have thought he was safe even if he dumped her.
